When you touch the fabric, you can feel the rigidity, the reaction force of the opponent, and it is full of elasticity. For example, for high-density fabrics made of elastic fibers and yarns, in order to make the fabric feel hard, we should choose thicker fibers, increase fiber modulus, and increase yarn tightness and weaving density.
Softness refers to the soft, light, fluffy, slippery and waxy hand feel, while the hardness, flatness and smoothness are weak. Make the fabric soft and improve the bulkiness of the yarn. Choose thinner yarns and the weaving density should not be too high.
The hand feel derived from coarse and hard fibers or strongly twisted yarns is mainly the hand feel of the fabric surface, and the overall rigidity of the fabric can enhance this hand feel. By twisting and using fibers with grooves or surfaces, a smooth feel can be obtained.
It comes from the softness and smoothness of fine wool, like the feel of cashmere. Waxity is the opposite of smoothness. Smoothness requires that the fibers on the surface of the fabric are small and distributed on the surface of the fabric in the form of loops or hairiness. There is a positive correlation between waxiness and bulkiness.
The fabric's ability to resist drape and stretch into a flat surface has nothing to do with elasticity. Selecting more rigid fibers and yarns to increase the weaving density will produce such performance characteristics.
Drape refers to the ability of the fabric to sag to form a curved surface under its own action. If the fabric can sag into a smooth, uniform curvature or evenly corrugated surface, it is said that the drape of the fabric is good.
